  1. SuperJANET5 Enabling Education and Research Roland Trice r.trice@ukerna.ac.uk

  2. Introduction to JANET • The Education Internet in the UK • HE, FE, Schools (via LEA networks) Research Institutes, and others • Over 1000 institutions • Complete Internet connectivity • SuperJANET4 • 10 Gbit/s SDH backbone • Delivers service to 20 regional networks • Regional networks connect individual institutions HEAnet National Networking Conference 2006

  3. The Requirement: Key issues • Network reliability and resilience • RNs connected by single link remained a concern • Demand for bandwidth • Power users • Pent up demand from FE • Enlarging the user base • The usual growth • Protect the interests of diverse communities • Flexible provisioning • Enhance network monitoring services HEAnet National Networking Conference 2006

  4. SJ5 must deliver • RELIABILITY • SCALABILITY • SEPARABILITY • FLEXIBILITY • VISIBILITY END-TO-END Achievable with a flexible transmission platform built on optical fibre HEAnet National Networking Conference 2006

  5. Infrastructure procurement • Negotiated Procedure • We know what we want • Flexible transmission system • Fibre and WDM equipment • Dedicated to SuperJANET • We didn’t know how we wanted it provided • Lease dark fibre & light it ourselves • Managed service from a Telco • We didn’t know if the market would deliver HEAnet National Networking Conference 2006

  6. Infrastructure procurement • Pre-qualification Q4 2004 • Six suppliers short-listed • Negotiate form of ITT with all six Q1/2 of 2005 • Launch ITT June 2005 • Only to short-listed suppliers • Contract awarded to Verizon (MCI) end of 2005 HEAnet National Networking Conference 2006

  7. Router procurement • Met with MCI in mid 2003 • Avici, Axiowave, Caspian, Chiaro, Hyperchip, Procket • Informal talks with suppliers in Q3/4 2003 • RFI document issued in early 2004 • Evaluate features of carrier class routers • Hands-on testing of • Chiaro Enstara, Cisco CRS-1, Juniper T-640, Procket PRO 8000 HEAnet National Networking Conference 2006

  8. Router procurement • Open procurement launched in Sept 2005 • Awarded to Lucent Technology January 2006 • Juniper T-640 routers • Carrier Class • >1000 in service world wide • 40 Gbit/s demonstrated by Juniper and Verizon • Available as a product now • Very good deal, Driving down the cost of ownership HEAnet National Networking Conference 2006

  9. Router marketplace • To date • Axiowave, Chiaro & Hyperchip have ceased trading • Procket bought up by Cisco • A week before RFI test • Caspian has moved out of the carrier space HEAnet National Networking Conference 2006

  10. Core Infrastructure • Six C-PoPs • Like SJ4 without Cosham and Edinburgh • Fibre network dedicated to SuperJANET5 • Single pair of fibres • Protection at the IP layer • Dedicated WDM transmission equipment • Operated by Verizon initially • UKERNA may manage circuit provision later in the project HEAnet National Networking Conference 2006

  11. Core Infrastructure • Ciena Corestream DWDM equipment • 80 wavelenghts per fibre • 10Gbit/s now, 40 Gbit/s in 2008 • Pilot on SJ5 core in 2007 • Core circuits grouped into ten bands of eight • Bands add/dropped at C-PoPs or at OADM sites HEAnet National Networking Conference 2006

  12. Core Network Design • Core Network consists of three basic components: • Core Terminal sites – Six blue locations • Flexible OADM sites (Optical Add Drop) – Eight white locations • Optical Amplification sites –Eleven locations, not shown HEAnet National Networking Conference 2006

  13. Core Traffic Provision • 10Gbit/s circuits are provisioned using two transponders only • No Regeneration needed  • Each circuit would have to be regenerated separately • Expensive • Optical amplification still needed every 80 KM or so • Telehouse & Telecity part of the core • Peerings to UK and Global Internet HEAnet National Networking Conference 2006

  14. Connecting Regional Networks • Two IP production circuits delivered to each RN • Delivery to diverse locations in the RN • One 10 Gbit/s research circuit • Connected to UKLight SDH mux • Two connection methods • Collector Arc • Point-point fibre through RNEPs linking C-PoPs • Single point-to-point fibre • Fibre from RNEP into the core HEAnet National Networking Conference 2006

  16. Production 2.5 Gbit/s circuit presented on muxponder cards at Newcastle Circuit is aggregated onto a 10 Gbit/s wavelength using an aggregation card The 10 Gbit/s wavelength is added into to the core network at the Verizon node in Newcastle and transported to the Glasgow C-PoP over the Corestream equipment. It is dropped out of the Glasgow Corestram into another 4200 at the Glasgow C-PoP The 2.5 Gbit/s circuit is de-muxed by a muxponder card and presented to the core router 10 Gbit/s research circuit Point to point fibre Verizon Glasgow Verizon Newcastle Newcastle University Regional Network Carried over collector arc Core network HEAnet National Networking Conference 2006

  24. Migration • 1st Regional Networks migrated on 31st November • Aggressive timetable • Tuesdays and Thursday mornings • Due to complete before Christmas 2006 • SuperJANET4 to continue until March 2007 • Contingency • Migrate research projects HEAnet National Networking Conference 2006

  25. Meeting the requirement: Reliability • Reduce single points of failure • Diverse fibre routing in the core • Dual connection of Regional Networks • Carrier class optical and routing equipment • SDH technology • In the core and out to the regional networks • Rapid failure detection and recovery • Detect latent problems HEAnet National Networking Conference 2006

  26. Meeting the requirement: Scalability • Ability to expand capacity • Where it’s needed • When it’s needed • 40 Gbit/s trial in early 2007 • Predictable cost • Marginal cost for transmission channels • Significant discount for router equipment • Not clawed back in maintenance charges HEAnet National Networking Conference 2006

  27. Meeting the requirement: Separability • Hard multiplexing of bandwidth channels • Production services firewalled from research infrastructures HEAnet National Networking Conference 2006

  28. Meeting the requirement: Flexibility • Deliver bandwidth quickly • In weeks rather than months • With a variety of interfaces and bandwidths • 10 and 2.5 Gbit/s SDH • 10 and 1 GE (LAN-PHY and WAN-PHY) • Temporary arrangements may become practical HEAnet National Networking Conference 2006

  29. Meeting the requirement: Visibility • Ability to monitor network in more detail • Operational monitoring • Research projects • Optical taps • Monitor all router interfaces at Reading and London • Issues of confidentiality have been addressed HEAnet National Networking Conference 2006
